Algoritmo diagnóstico y terapéutico de las lesiones esplácnicas provocadas durante la inserción de sondas pleurales

Introducción: La colocación de sondas pleurales es un procedimiento quirúrgico frecuente que puede tener graves complicaciones, las cuales dependen en la mayoría de los casos de la experiencia del operador, el tamaño del tubo y el uso de imágenes para guiar la inserción. Objetivo: Describir las principales lesiones esplácnicas provocadas durante la inserción de sondas pleurales y presentar algoritmos para el diagnóstico precoz y el tratamiento oportuno de estas iatrogenias. Métodos: Se realizó una revisión descriptiva narrativa durante el primer trimestre del año 2023. Se utilizaron las bases de datos electrónicas PubMed, LILACS, EBSCO y Cochrane. Se revisaron artículos publicados desde 1984 hasta el 2022. Se procuró que la mayoría de la información se enmarcara en un período no mayor de 10 años de antigüedad. Desarrollo: De las lesiones esplácnicas de la cavidad torácica, la de pulmón es la más frecuente y puede conducir a sangrado o fuga aérea persistente. Las lesiones vasculares son graves y pueden provocar la muerte si no se toman las medidas pertinentes. Se han descrito lesiones de órganos huecos de la cavidad abdominal que suelen ser parte de una hernia diafragmática. Dentro de las lesiones esplácnicas en el abdomen más frecuentes están la hepática y la esplénica. Conclusiones: Estas lesiones son prevenibles y se debe tener en cuenta su mecanismo de producción para evitarlas. Para este fin recomendamos una selección cuidadosa del sitio de inserción, realizar una confirmación adecuada de la posición de la sonda, manipularla cuidadosamente y monitorear constantemente al paciente.

Introduction: Chest tube insertion is a frequent surgical procedure that can have serious complications, which depend mostly on the practitioner's experience, the tube's size and the use of imaging to guide the insertion. Objective: To describe the main splanchnic injuries caused during chest tube insertion, as well as to present algorithms for early diagnosis and timely treatment of these types of iatrogeny. Methods: A descriptive narrative review was performed during the first quarter of the year 2023. The electronic databases PubMed, LILACS, EBSCO and Cochrane were used. Articles published from 1984 to 2022 were reviewed. Most of the information was secured to be framed within a period of no more than 10 years. Development: Among the splanchnic injuries within the thoracic cavity, lung injury is the most frequent and may lead to bleeding or persistent air leak. Vascular injuries are severe and can lead to death if appropriate measures are not taken. Injuries to hollow organs of the abdominal cavity have been described to be usually part of a diaphragmatic hernia. Among the most frequent splanchnic lesions within the abdomen are the hepatic and splenic injuries. Conclusions: These lesions are preventable and their mechanism of production should be taken into account in order to avoid them. To achieve this, we recommend that the insertion site be carefully selected and that the tube's position be adequately confirmed, as well as the careful handling of the tube and the constant monitoring of the patient.

Clinical-epidemiological evaluation of victims of thoracic trauma in a reference hospital in Aracaju-SE / Avaliação clínico-epidemiológica dos pacientes vítimas de trauma torácico em um hospital de referência de Aracaju-SE

ABSTRACT Introduction: thoracic trauma is defined as anything that involves the rib cage, the musculoskeletal framework that houses the heart, lungs, pleurae and mediastinal structures. It can be superficial or immediately lifethreatening for victims. In Brazil, most assistance is due to urban violence. Objective: evaluate the clinical and epidemiological aspect of patients who are victims of thoracic trauma treated at Hospital de Urgência de Sergipe, Aracaju/SE, Brazil. Method: cross-sectional, observational and prospective study, carried out for eleven months, with 100 polytraumatized patients. A semi-structured form was applied, and the data were systematized, analyzed and statistically tested considering a 5% margin of error. Results: 85% of the patients were male, with a mean age of 39.3 and an age range of 30 to 49 years; 57% of them had incomplete primary education, 70% had a family income of up to 2 minimum wages and 41% were from Greater Aracaju. As for the mechanism of trauma, 33% were car-related, with blunt trauma as the main mechanism, and rib fractures as the main consequence. Among penetrating injuries, CWI (26%) and GSW (21%) were the most prevalent, with hemothorax being the main consequence. Most patients underwent thoracostomy (59%). Conclusion: the profile found was of young men, victims of urban violence. The thoracostomy was resolving in most cases and should be instituted promptly when necessary. A smaller number of patients may require thoracotomy, especially in the presence of hemodynamic instability.

RESUMO Introdução: o trauma torácico é definido como toda aquele que envolve a caixa torácica, arcabouço osteomuscular que aloja o coração, os pulmões, as pleuras e as estruturas do mediastino. Pode ser superficial ou causar risco de vida imediato às vítimas. No Brasil, a maioria dos atendimentos é decorrente da violência urbana. Objetivo: avaliar o aspecto clínico-epidemiológico dos pacientes vítimas de trauma torácico atendidos no Hospital de Urgência de Sergipe, Aracaju/SE, Brasil. Métodos: estudo transversal, observacional e prospectivo, realizado durante onze meses, com 100 pacientes politraumatizados. Formulário semiestruturado foi aplicado, e os dados sistematizados, analisados e testados estatisticamente considerando-se a margem de erro de 5%. Resultados: 85% dos pacientes eram do gênero masculino, com idade média de 39,3 e faixa etária de 30 a 49 anos; 57% deles possuíam ensino fundamental incompleto, 70% tinham renda familiar de até 2 salários mínimos e 41% eram provenientes da Grande Aracaju. Quanto ao mecanismo de trauma, 33% foi automobilístico, tendo como principal mecanismo o trauma contuso, e a principal consequência a fratura de arcos costais. Dentre os ferimentos penetrantes, os FAB (26%) e FAF (21%) foram os mais prevalentes, sendo o hemotórax sua principal consequência, sendo maioria dos pacientes submetida a toracostomia (59%). Conclusão: o perfil encontrado foi de homens, jovens, vítimas da violência urbana. A toracostomia foi resolutiva na maioria dos casos e deve ser instituída prontamente quando necessário. Uma menor parte dos pacientes necessitou de toracotomia, principalmente na presença de instabilidade hemodinâmica.

Animal model-based simulation training for three emergent and urgent operations of penetrating thoracic injuries / 中华创伤杂志(英文版)

PURPOSE@#To develop animal models of penetrating thoracic injuries and to observe the effects of the animal model-based training on improving the trainees' performance for emergent and urgent thoracic surgeries.@*METHODS@#With a homemade machine, animal models of lung injuries and penetrating heart injuries were produced in porcine and used for training of chest tube drainage, urgent sternotomy, and emergent thoracotomy. Coefficient of variation of abbreviated injury scale and blood loss was calculated to judge the reproducibility of animal models. Five operation teams from basic-level hospitals (group A) and five operation teams from level III hospitals (group B) were included to be trained and tested. Testing standards for the operations were established after thorough literature review, and expert questionnaires were employed to evaluate the scientificity and feasibility of the testing standards. Tests were carried out after the training. Pre- and post-training performances were compared. Post-training survey using 7-point Likert scale was taken to evaluate the feelings of the trainees to these training approaches.@*RESULTS@#Animal models of the three kinds of penetrating chest injuries were successfully established and the coefficient of variation of abbreviated injury scale and blood loss were all less than 25%. After literature review, testing standards were established, and expert questionnaire results showed that the scientific score was 7.30 ± 1.49, and the feasibility score was 7.50 ± 0.89. Post-training performance was significantly higher in both group A and group B than pre-training performance. Post-training survey showed that all the trainees felt confident in applying the operations and were generally agreed that the training procedure were very helpful in improving operation skills for thoracic penetrating injury.@*CONCLUSIONS@#Animal model-based simulation training established in the current study could improve the trainees' performance for emergent and urgent thoracic surgeries, especially of the surgical teams from basic-level hospitals.

Neumatocele traumático: una presentación inusual del trauma cerrado de tórax en paciente de 21 años / Traumatic pneumatocele: an unusual presentation of blunt chest trauma in a 21-year-old patient

El neumatocele traumático, o pseudoquiste pulmonar traumático, es una complicación infrecuente del trauma cerrado de tórax, caracterizada por lesiones cavitadas únicas o múltiples de paredes fibrosas bien delimitadas, sin revestimiento epitelial. Representa un reto diagnóstico ante la prevalencia de etiologías más frecuentes de cavitación pulmonar, presentación clínica inespecífica y el carácter subreportado de la patología. Se presenta el caso de un paciente de 21 años, con cuadro clínico de fiebre y dolor torácico posterior a traumatismo contuso por accidente en motocicleta, con identificación de una lesión cavitada rodeada de vidrio esmerilado, ubicada en lóbulo superior derecho en tomografía de tórax. Se ofreció tratamiento antibiótico ante la sospecha clínica de sobreinfección. Sin embargo, se atribuyó la alteración pseudoquística pulmonar al antecedente traumático. En ocasiones las cavitaciones pulmonares postrauma no son identificadas en la atención inicial, por ende, es fundamental la evaluación clínica e imagenológica subsecuente.

Traumatic pneumatocele, or traumatic pulmonary pseudocyst, is a rare complication of blunt chest trauma, characterized by multiple or unique cavitary lesions, with well-defined fibrous walls without epithelial lining. It represents a diagnostic challenge due to the higher prevalence of other etiologies of lung cavities, nonspecific clinical features and the under-reported nature of this pathology. We present the case of a 21-year-old male with fever and chest pain after a blunt chest trauma in a motorcycle accident, with identification of a cavity in the right upper lobe, surrounded by ground glass opacities. Antibiotic therapy was administered after clinical suspicion of superinfection, however, the cavitary lesion was attributed to the trauma. Occasionally, traumatic pulmonary pseudocysts are not identified during initial assessment, therefore, clinical and imagenologic follow-up is essential.

RESUMEN Fundamento el traumatismo torácico es un cuadro clínico complejo que puede comprometer la vida del paciente. Por ello es de interés su estudio y análisis. Objetivo caracterizar los pacientes con traumatismo torácico en el servicio de Cirugía General. Métodos estudio descriptivo, prospectivo, de serie de casos, que incluyó a pacientes que ingresaron con el diagnóstico de traumatismo torácico, en el servicio de Cirugía General del Hospital General Universitario Dr. Gustavo Aldereguía Lima, de Cienfuegos, en el período enero/2019 a diciembre/2020. Las variables analizadas fueron: edad, sexo, comorbilidades, exámenes imagenológicos, agente causal, lesión torácica, tipo de tratamiento, tipo de traumatismo torácico y estado al egreso. Resultados el trauma de tórax fue más frecuente en el sexo masculino, a partir de la cuarta década de vida en pacientes sanos. El examen imagenológico más usado fue la radiografía simple de tórax; y el agente causal predominante, la herida por arma blanca. Las lesiones torácicas más frecuentes resultaron el enfisema subcutáneo y el hemoneumotorax, así como la pleurostomía fue el tipo de tratamiento más usado. Predominó el traumatismo torácico aislado, siendo las lesiones abdominales las más asociadas. La mayoría de los pacientes egresaron vivos. Conclusión el trauma torácico constituye una patología altamente desafiante, por lo complejas que pueden llegar a ser las lesiones derivadas de él; se presenta con mayor frecuencia en hombres sanos. Cuando se asocia a otras lesiones aumenta la mortalidad.

Background chest trauma is a complex clinical picture that can compromise the patient's life. Therefore, its study and analysis is of interest. Objective to characterize patients with chest trauma in the General Surgery service. Methods descriptive, prospective, case series study which included patients admitted with a diagnosis of chest trauma, in the General Surgery Service at the Dr. Gustavo Aldereguía Lima General University Hospital, Cienfuegos, from January 2019 to December2020. The analyzed variables were: age, sex, comorbidities, imaging tests, causal agent, chest injury, type of treatment, type of chest trauma, and discharge status. Results chest trauma was more frequent in males, from the fourth decade of life in healthy patients. The most used imaging test was the simple chest X-ray; and the predominant causal agent, the stab wound. The most frequent chest injuries were subcutaneous emphysema and hemopneumothorax, and pleurostomy was the most used type of treatment. Isolated chest trauma prevailed, with abdominal injuries being the most associated. Most of the patients were discharged alive. Conclusion thoracic trauma constitutes a highly challenging pathology, due to how complex the injuries derived from it can become; It occurs more frequently in healthy men. When associated with other injuries, mortality increases.

Traumatismo de grandes vasos del tórax: tratamiento quirúrgico con soporte de circulación extracorpórea / Injury of the great vessels of the chest: surgical treatment with cardiopulmonary bypass support: clinical cases

Resumen Objetivo: Presentar dos casos en que se empleó como soporte la circulación extracorpórea (CEC) durante cirugía por traumatismo torácico con lesión de grandes vasos del tórax (TTLGV). Materiales y Método: Se presentan dos casos con TTLGV en que se empleó cirugía con CEC. Resultados: Caso 1; hombre de 31 años con TTLGV por cuerpo extraño (tubo pleural) intracavitario del tronco de la arteria pulmonar izquierda, con entrada a través de parénquima pulmonar, en que se realizó cirugía abierta para retiro de cuerpo extraño más toractotomía pulmonar utilizando CEC como soporte. Caso 2; hombre de 21 años con TTLGV contuso y lesión de aorta en unión sino tubular, en que se realizó cirugía abierta y reemplazo de aorta ascendente con prótesis y uso CEC como soporte. Discusión: El uso de CEC como soporte es una alternativa para sustituir la función cardíaca y/o pulmonar durante cirugías excepcionales de reparación de TTLGV. Conclusión: El uso de técnicas de asistencia circulatoria como soporte durante la cirugía de reparación de TTLGV ocurre en casos muy seleccionados, siendo una alternativa ante lesiones particularmente complejas.

Aim: To present two cases of thoracic trauma with great vessel injury (TTGVI) surgeries where extracorporeal circulation (ECC) was employed. Materials and Method: Two TTGVI cases are presented and ECC during surgery was used in both. Results: Case 1; 31-year-old man with TTGVI due to an intracavitary foreign body (pleural tube) in the left pulmonary artery trunk, which entered through lung parenchyma. An open surgery was performed to remove the foreign body with pulmonary tractotomy using ECC as support. Case 2; 21-year-old man with blunt TTGVI and aortic injury at sinotubular junction. An open surgery with ascending aorta prosthesis replacement was performed, using ECC as support. Discussion: The use of ECC as support is an alternative to replace cardiac and/or pulmonary function during exceptional TTGVI reparation surgeries. Conclusión: The use of circulation assist techniques as support during TTGVI repair surgery occurs in highly selected cases, being an alternative to face very complex injuries.

Cirugías por traumatismo torácico: caracterización y variables asociadas a mortalidad / Thoracic trauma surgery: indications, findings and mortality associated variables

Resumen Introducción: El traumatismo torácico (TT) es la causa de aproximadamente un cuarto de las muertes por traumatismos. Los pacientes tratados con cirugía por traumatismo torácico (CTT) presentan un amplio espectro de características y pronósticos. Objetivos: Describir características clínicas, indicaciones, temporalidad, morbilidad, mortalidad y las variables asociadas a mortalidad en pacientes con CTT. Materiales y Método: Estudio observacional de pacientes tratados con CTT, período enero-1981 a diciembre-2019. Revisión de protocolos prospectivos de TT y base de datos. Se realizó regresión logística para variables asociadas a mortalidad. Se utilizó SPSS25® con prueba chi-cuadrado para comparar clasificación, tipo de TT y su distribución temporal, considerando significativo p < 0,05. Resultados: En total 808 casos (18,2%) de 4.448 TT requirieron CTT. Fueron hombres 767 (94,9%) y la edad promedio fue 31,5 ± 13,8 años. El traumatismo fue penetrante y por arma blanca en la mayoría de los casos. Fueron politraumatizados 164 (20,3%). La cirugía fue urgente en 474 (58,7%), precoz en 41 (5,0%) y diferida en 293 (36,3%) casos. La mortalidad global fue de 6,7% y fue significativamente mayor en TT contusos, politraumatizados y en cirugía urgente. La mortalidad fue 9,7% en CTT urgente, 4,9% en precoz y 2,0% en diferida (p < 0,001). Se observaron variables independientes asociadas a mortalidad. Conclusión: En nuestra serie, las CTT se realizaron principalmente en hombres jóvenes con TT penetrantes. Correspondieron a un grupo heterogéneo en cuanto a las indicaciones, hallazgos y lesiones intratorácicas y/o asociadas. Múltiples variables demostraron influir significativamente en la mortalidad de los pacientes tratados con CTT.

Background: Thoracic Trauma (TT) is the cause of approximately a quarter of trauma deaths. The patients who undergo Thoracic Trauma Surgery (TTS) present a wide spectrum of characteristics and prognosis. Aim: To describe clinical characteristics, indications, temporality, morbidity, mortality and mortality associated variables in TTS patients. Materials and Method: Observational study of TT hospitalized patients, period January-1981 to December-2019. A review of operation notes and database was done. A logistic regression for mortality associated variables was made. To compare classification, type of TT and its temporal distribution, SPSS25® with chi-square test was used, considering significant p < 0.05. Results: A total of 808 (18.2%) of 4.448 TT patients required TTS, 767 (94.9%) were men with average age: 31.5 ± 13.8. The trauma was penetrating trauma due to a stab in most cases, 164 (20.3%) were polytraumatized. The surgery was urgent in 474 (58.7%), early in 41 (5.0%) and delayed in 293 (36.3%) cases. The global mortality was 6.7% and was significantly higher in the blunt TT, polytrauma, urgent and early surgery patients. Mortality in urgent TTS was 9.7%, early 4.9% and 2.0% in delayed (p < 0.001). Independent variables associated with mortality were observed. Conclusions: In our series, TTS were performed mainly in young men with penetrating TT. The group was heterogeneous regarding surgical indications, findings and intrathoracic or associated injuries. Multiple variables showed to influence significantly on mortality in patients who underwent TTS.

Objective:To investigate the risk factors of severe chest trauma complicated by acute respiratory distress syndrome (ARDS).Methods:A case control study was conducted to analyze the clinical data of 120 patients with severe chest trauma admitted to 909th Hospital of Joint Logistics Support Force (Affiliated Dongnan Hospital of Xianmen University Medical College) from January 2018 to December 2020. There were 75 males and 45 females; aged 21-72 years [(42.2±4.8)years]. The causes of injury were traffic injury in 57 patients, crush injury in 21, fall injury in 21, smash injury in 11 and others in 10. There were 34 patients accompanied by fracture of the limb, spine and pelvis, 23 by abdominal organ injury and 8 by head trauma, with the exception of simple thoracic trauma in 55 patients. The patients were divided into ARDS group ( n=25) and non-ARDS group ( n=95) according to the condition of concurrent ARDS. The two groups were compared regarding the gender, age, causes of injury, respiratory rate, lung contusion, lung infection, flail chest, chest abbreviated injury scale (AIS), hemothorax, blood pressure, partial arterial oxygen pressure (PaO 2), initial central venous pressure (CVP) on admission, combined fracture of the limb, spine and pelvis, combined head injury and combined abdominal organ injury. The correlation between the above indexes and ARDS after severe chest trauma was analyzed by univariate analysis. Multivariate Logistic regression analysis was used to determine the independent risk factors for ARDS after severe chest trauma. Results:Univariate analysis showed a positive correlation of ARDS with age, respiratory rate, lung contusion, lung infection, flail chest, chest AIS, hemothorax, blood pressure, PaO 2, initial CVP on admission, combined fracture of the limb, spine and pelvis and combined abdominal organ injury ( P<0.05 or 0.01), but not with gender, causes of injury or combined head injury (all P>0.05). Multivariate Logistic regression analysis revealed that age ≥60 years ( OR=2.45, 95% CI 1.81-7.50, P<0.01), dyspnea (respiratory rate ≥28 times/minute or <10 times/minute) ( OR=9.55, 95% CI 2.26-9.38, P<0.01), lung contusion ( OR=6.78, 95% CI 1.84-6.96, P<0.01), lung infection ( OR=27.71, 95% CI 11.97-64.14, P<0.01), flail chest ( OR=8.97, 95% CI 2.29-14.97, P<0.01), chest AIS score ( OR=5.77, 95% CI 2.85-9.20, P<0.01), above medium amount of hemothorax ( OR=6.84, 95% CI 1.69-13.39, P<0.01), blood pressure <90 mmHg ( OR=7.93, 95% CI 1.64-11.84, P<0.01), PaO 2<60 mmHg ( OR=6.39, 95% CI 1.06-9.47, P<0.01) and absent initial CVP on admission ( OR=4.56, 95% CI 1.86-8.44, P<0.01) were significantly correlated with ARDS. Conclusion:Age ≥60 years, dyspnea (respiratory rate ≥28 times/minute or <10 times/minute), lung contusion, lung infection, flail chest, chest AIS, above medium l amount of hemothorax, blood pressure <90 mmHg, PaO 2<60 mmHg and absent initial CVP on admission are independent risk factors for ARDS in patients with severe chest trauma.

Research progress in chest trauma scoring systems / 中华创伤杂志

Chest trauma accounts for 10%-15% of total trauma and is responsible for approximately 25% of trauma-related deaths. Standard and accurate assessment of trauma severity is the basis for effective treatment. The application of chest trauma scoring systems to evaluate the severity of trauma is of great significance to prediction of complication and prognosis, clinical decision making and treatment optimization. The chest trauma scoring systems are varied with different functions and characteristics. When performing injury evaluation, an appropriate chest trauma scoring system should be selected according to the injury mechanism, injury site and needs of diagnosis and treatment. The authors review the application scope, scoring methods and research status of different chest trauma scoring systems, in order to provide references for more rational use of trauma scoring systems in clinical evaluation and treatment of chest trauma.

Value of cardiac magnetic resonance in the diagnosis of myocardial contusion / 中华创伤杂志

Objective:To evaluate the diagnostic value of cardiac magnetic resonance (CMR) in myocardial contusion.Methods:A case-control study was performed on 42 patients with blunt chest injury treated in Affiliated Hospital of Hangzhou Normal University from September 2018 to January 2021. There were 24 males and 18 females, with the age range of 23-66 years [(44.2±10.9)years]. The patients were divided into myocardial contusion group ( n=20) and non-myocardial contusion group ( n=22) according to the clinical diagnostic criteria of myocardial contusion (cardiac troponin I>0.06 ng/ml). All the patients underwent CMR examination within 7 days after hospitalization, and eletrocardiography (ECG) as well as transthoracic echocardiography (TTE) examinations with 24 hours. Abnormal findings on CMR, ECG and TTE were compared between the two groups. The receiver operating characteristic (ROC) curve was used for the comparison of the diagnostic efficacy of CMR, ECG and TTE for myocardial contusion. The area under the curve (AUC), sensitivity, specificity, positive predictive value and Youden index of CMR, ECG and TTE were calculated, respectively. Results:There were 15 patients (75%) presenting CMR abnormalities in myocardial contusion group compared to 2 patients (9%) in non-myocardial contusion group ( P<0.01). CMR abnormalities mainly included myocardial oedema, ischemia or hemorrhage, which were located in the left ventricle of 12 patients (71%), right ventricle of 3 (18%) and ventricular septal of 3 (12%). There were 12 patients (60%) showing ECG abnormalities in myocardial contusion group compared to 7 patients (32%) in non-myocardial contusion group ( P>0.05). Abnormal ECG changes included 8 patients (42%) with sinus tachycardia or bradycardia, 5 (26%) with ST-T changes, 3 (16%) with atrial premature beat, 2 (11%) with bundle branch block and 1 (5%) with frequent premature ventricular contractions. There were 10 patients (50%) showing TTE abnormalities in myocardial contusion group compared to 9 patients (41%) in non-myocardial contusion group ( P>0.05). TTE abnormalities manifested as left ventricular diastolic dysfunction in 12 patients (63%) and wall motion abnormalities in 7 (37%). The AUC of CMR, ECG and TTE for diagnosing myocardial contusion was 0.83 (95% CI 0.70-0.96), 0.64 (95% CI 0.47-0.81) and 0.55 (95% CI 0.70-0.72), respectively. For CMR, ECG and TTE, the diagnostic sensitivity was 75.0%, 60.0% and 50.0%, with the specificity of 91.0%, 68.2% and 59.1%, the positive predictive value was 88.2%, 63.2% and 52.6%, and the Youden index of 66.0, 28.2 and 9.1, respectively. Conclusion:CMR can accurately detect myocardial contusion, with better diagnostic performance than ECG and TTE as well as relatively higher sensitivity and specificity, indicating that CMR has great value for clinical diagnosis of myocardial contusion.

Clinical guideline on first aid for blast injury of the chest (2022 edition) / 中华创伤杂志

Blast injury of the chest injury is the most common wound in modern war trauma and terrorist attacks, and is also the most fatal type of whole body explosion injury. Most patients with severe blast injury of the chest die in the early stage before hospitalization or during transportation, so first aid is critically important. At present, there exist widespread problems such as non-standard treatment and large difference in curative effect, while there lacks clinical treatment standards for blast injury of the chest. According to the principles of scientificity, practicality and advancement, the Trauma Society of Chinese Medical Association has formulated the guidance of classification, pre-hospital first aid, in-hospital treatment and major injury management strategies for blast injury of the chest, aiming to provide reference for clinical diagnosis and treatment.

Attach great importance to the role of extracorporeal membrane oxygenation in the rescue of severe cardiopulmonary trauma / 中华创伤杂志

The principle of early treatment for severe cardiopulmonary trauma is to correct respiratory and circulatory insufficiency, especially for the type of injury caused by various types of trauma such as severe alveolar oxygen exchange dysfunction, intrapulmonary hemorrhage, massive pulmonary atelectasis and extensive subendocardial hemorrhage. Conventional treatment is not effective, and the timely use of cardiopulmonary replacement function of extracorporeal membrane oxygenation (ECMO) can better overcome this problem. ECMO is a life-support technology for patients with severe cardiopulmonary insufficiency, which can partially replace the functions of heart pumping and lung oxygenation for a longer period of time so as to creat opportunities for waiting for organ function recovery and providing bridging therapy. The author discusses the mechanism of action and clinical application of ECMO and the application, deficiencies and countermeasures of ECMO in severe cardiopulmonary trauma so as to provide some theoretical and practical references for improving the quality and process of ECMO treatment.

Chinese expert consensus on diagnosis, treatment and prevention of venous thrombus embolism associated with chest trauma (2022 version) / 中华创伤杂志

Chest trauma is one of the most common injuries. Venous thromboembolism (VTE) as a common complication of chest trauma seriously affects the quality of patients′ life and even leads to death. Although there are some consensus and guidelines on the prevention and treatment of VTE at home and abroad, the current literatures lack specificity considering the diagnosis, treatment and prevention of VTE in patients with chest trauma have their own characteristics, especially for those with blunt trauma. Accordingly, China Chest Injury Research Society and editorial board of Chinese Journal of Traumatology organized relevant domestic experts to jointly formulate the Chinese expert consensus on the diagnosis, treatment and prevention of chest trauma venous thromboembolism associated with chest trauma (2022 version). This consensus provides expert recommendations of different levels as academic guidance in terms of the characteristics, clinical manifestations, risk assessment, diagnosis, treatment, and prevention of chest trauma-related VTE, so as to offer a reference for clinical application.

Predictors of pleural complications in trauma patients undergoing tube thoracostomy: A prospective observational study / Fatores preditivos de complicações pleurais em vítimas de trauma submetidas à drenagem pleural: Estudo prospectivo observacional

ABSTRACT Objective: to identify variables related to pleural complications in patients undergoing tube thoracostomies due to traumatic injuries. Method: we conducted a prospective observational study from May/2019 to January/2021 including adult trauma patients submitted to tube thoracostomies after hospital admission. Patients undergoing thoracotomies as the initial treatment were not included. We excluded patients with suspected and confirmed COVID-19 diagnosis during the hospitalization. Pleural complications were defined as clotted hemothorax, residual pneumothorax and empyema. Students t, Mann Whitneys, Chi square and Fishers exact test were used to compare variables between groups. We considered p<0.05 as significant. Results: we analyzed 68 patients. The mean age was 36.0 + 12.6 years and 91.2% were male. The mean RTS and ISS were, respectively, 7.0 ± 1.6 and 15.9 ± 7.6. The most frequent trauma mechanism was stab wounds in 50.0%, followed by blunt trauma in 38.2%. The severity of thoracic injuries was stratified (AIS) as 2 (4.4%), 3 (80.9%), 4 (13.2%), e 5 (1.5%). Pleural complications happened in 14 (20.5%) patients, being clotted / residual hemothorax (11.8%), residual pneumothorax (4.4%), empyema (2.9%) and miscellaneous (1.4%). These patients were treated by thoracoscopy (5), thoracotomy (3), chest re-drainage (3) and clinical measures alone (3). There was a significant association between pleural complications with the time of permanence (p<0,001) and the necessity of relocation (p<0,001) of the drain. Conclusion: the predictors of pleural complications in this series were time of permanence and the necessity of relocation of the drain.

RESUMO Objetivo: identificar as variáveis relacionadas às complicações pleurais em vítimas de trauma submetidas a drenagem torácica. Método: estudo observacional prospectivo entre maio/2019 e janeiro/2021, incluindo adultos submetidos a drenagem torácica após a admissão hospitalar para tratamento de lesões traumáticas. Pacientes que desenvolveram COVID19 foram excluídos. As complicações pleurais foram caracterizadas como: pneumotórax residual, hemotórax residual / coagulado e empiema pleural. Comparamos as variáveis coletadas entre os grupos de pacientes com e sem estas complicações. Os testes t de Student, Mann Whitney, Chi quadrado e Fisher foram utilizados para análise estatística. Foram considerados significativos valores de p<0,05. Resultados: analisamos 68 casos, com média etária de 36,0 + 12,6 anos, de RTS de 7,0 ± 1,6 e ISS de 15,9 ± 7,6, sendo 62 (91,2%) do sexo masculino. Trinta e quatro pacientes (50,0%) foram vítimas de ferimento por arma branca. O AIS das lesões torácicas foi classificado como 2 (4,4%), 3 (80,9%), 4 (13,2%), e 5 (1,5%). As complicações pleurais ocorreram em 14 casos (20,5%), sendo hemotórax residual / coagulado em 8 casos (11,8%), pneumotórax residual em 3 (4,4%), o empiema pleural em 2 (2,9%) e associações em 1 (1,4%). Estas complicações foram tratadas por videotoracoscopia (5 casos), toracotomia (3), redrenagem de tórax (3) e medidas clínicas apenas (3). A redrenagem de tórax (p<0,001) e o tempo de permanência do dreno (p<0,001) tiveram relação significativa com a presença de complicações pleurais. Conclusão: a redrenagem do tórax e o maior tempo de permanência do dreno foram associados às complicações pleurais.

Materials and Method: Retrospective descriptive study of patients operated on for SF between January 2015 and January 2020. We analyzed age, sex, morbid history, hemodynamics on admission, causal mechanism and characteristics of sternal injury, associated injuries, surgical indication and complications. Results: During the period, 9 patients were admitted to our hospital (7 men) from 21 to 91 years old. All were operated. Most were admitted with stable hemodynamics. The mechanism was always traumatic. The surgical indications were: intractable pain, alteration of ventilatory mechanics, flail chest, deformity and aid in the rehabilitation of spinal cord trauma. Discussion: SF is an infrequent pathology, its surgical resolution reported worldwide being even scarce. Conclusions: We present the first report of a series of cases of SF operated in Chile. Sternal osteosynthesis allows the management of EF with good functional results with a low morbidity rate. The results obtained are comparable to those observed in the international literature.

"Packing" torácico en urgencias torácicas / Thoracic packing in thoracic emergencies

RESUMEN El control de daños es un procedimiento en tres etapas en pacientes con riesgo vital. Primera etapa: laparotomía abreviada para el control de sangrados y contaminación. Segunda etapa: en cuidados críticos para corregir alteraciones fisiológicas y tercera etapa: con resolución definitiva de las lesiones. Se describió el empaquetamiento (packing) torácico como adaptación del empaquetamiento abdominal como procedimiento contemporizador y hemostático. El objetivo fue presentar nuestra experiencia con la cirugía de empaquetamiento torácico y mostrar su utilidad en la cirugía de control de daños en tórax. Las lesiones traumáticas de tórax pueden ir desde lesiones de leve entidad hasta lesiones graves que amenacen la vida del paciente. La decisión de empaquetar el tórax se adopta al tomar contacto con un paciente "in extremis". En conclusión, el empaquetamiento torácico se muestra eficaz para el control del sangrado en pacientes que no admiten medidas definitivas para él.

ABSTRACT Damage control is defined as an approach with 3 stages in patients with life-threatening injuries. Stage I: abbreviated laparotomy for hemorrhage and contamination control. Stage II: intensive care management to correct physiologic abnormalities; and stage III: definitive repair of injuries. Thoracic packing, an adaptation of abdominal packing, was described as a temporary procedure for hemostatic control. The aim of this study is to report our experience with thoracic packing and show its usefulness in thoracic damage control surgery. Traumatic chest injuries vary from minor trauma to life-threatening injuries. The decision to perform thoracic packing is made during the contact with a critically ill patient. In conclusion, packing is effective for bleeding control in critically ill patients who are not suitable for definitive treatment.
